Specification of Letters Patent.

Patented May 7, 1907.

Application filed June 30, 1906. Serial No. 324,182.

which the following is a specication, refer-y 'ence being had to the accompanying drawings, forming a aart hereof.

The oblect o this invention is to provide an attachment for routing machines and the like whereby suoli machines may be readily adapted to cut, rule or perform some other operation along a straight edge or in a straight line.

The invention is designed principally for use in connection with machines having an elbow lever for carrying a cutter or other working tool, such a machine, for instance, being shown and described in Letters Patent of the United States No. 622,832 dated April 1l, 1899, and granted to Ferdinand Wesel and in the present case the invention is illustrated as embodied in the machine shown and described in said Letters Patent.

ln the drawings Figure 1 is a plan view of the machine with the attachment in place thereon. Fig. 2 is a view in side elevation.

Fig. 3 is a detail elevation showing the shaft Y of a swiveling bracket for guiding one arm of the elbow lever, and some of the means for moving said shaft part of the figure being broken away and shown partly in section to illustrate the construction more clearly. Fig. 4 is a similar view of the same parts looking in a direction at right angles to the plane of Fig. 3. Figs. 5 and 6 are sectional views looking down upon the planes indicated by the lines 5 5 and 6 6 respectively in Fig. 3. Fig. 7 is a detail plan and Fig. 8 is a detail elevation, of a roller guide for the end of one arm of the elbow lever.

For the purpose of the present description,

f6 are pivoted to each other at f 7.

it will suffice to refer brieily to this machine. Using the same reference characters, in referring to this machine, as were used in said Letters Patent, it will be seen from Figs. l and 2 of the drawings that a table B is supported upon a pillar or standard A which in turn rests upon a base A. Above'the table an elbow lever is provided for carrying the working tool which, in the case of Letters Patent No. 622,832, is represented by the cutter h6 (not shown in the present drawings). This elbow lever has a disk-shaped base d which turns freely on a disk-shaped liange d mounted upon the table and said lever consists of a lever arm D and a second lever arm Fv .pivotally secured thereto. Suitable driving connections for the working tool are illustrated and described in said Letters Patent but need not be referred to herein.. As will be obvious, the working tool which is mounted upon the lever arm F, as illustrated in said Letters Patent, may be moved into any position above the table by moving the front or handle end F2 of the lever arm F which in the present case is shown broken off and which rests upona guide rail G at the front of the table. lt 'will be clear that in order to move the working tool or cutter along a straight edge or in other words to move the arm F of the elbow lever or that portion of the arm F which carries the working tool or cutter in a straight line, will require the provision of some means for guiding the same. Such means, it is the object of the present invention to provide and they will now be described.

In the first place, in order that that portion of the arm F which carries the working tool or cutter may move in a straight line, it must be capable, as will be obvious, of a certain degree of movement of translation with respect to the pivotal point of the arm F upon the arm D. For this purpose the arm F is jointed and the two members thereof f5 and Moreover, one of the members as f 6 is provided with an arc-shaped slot fs in which a thumb screw f 9 having a flange flo and threaded upon the ICO member f5 is adapted to work, the said j permitting the free movement of the member f5 when it is desired to move that member along a straight line.

The means for guiding the member f5 in a straight line comprises a swiveling bracketU at one end and some such a device as a roller V at the other end. The swiveling bracket is provided with a projection u which serves as a guiding piece and co-operates with a long guideway or slot f 11 formed in the underside of the member f 5 to guide the rear end of the member f5. This bracket arm u may be mounted upon a suitable stationary base fu. which is provided with` suitable means such as a lug or detent u2 adapted to engage in a corresponding recess in the bracket arm to hold the latter firmly in operative position. The bracket arm is moved into and out of operative position by handle W preferably near connected with means for rotating the bracket and for raising and lowering the same upon the lug or detent u2. The means for rotating the bracket preferably comprise a rack w meshing with a pinion us keyed to a shaft w* which is rigidly secured to the bracket arm and which is journaled in a bracket a5 secured to the pillar A. This bracket may be formed with a long guideway for the rack w and also with a second long guideway for thereception of a corresponding fiange w upon a sliding wedge w2 which serves at the proper time to draw the bracket arm U downwardly so that its recess fits upon the detent u2 against the action of a'spring u coiled around the shaft u4 between the bracket a5 and a collar a7 fast upon said shaft. Co-

' operating with the sliding wedge w2 is a collar w3 fitted loosely upon the lower end of the shaft and held thereon by nuts wl. The sliding wedge w2 preferably has two arms or members which embrace the shaft w* and the collar w3 is provided with a projection w5 which fits between these two arms or members and is thus held from any rotation relative to the sliding wedge. of said collar where it co-operates with each arm of the sliding wedge is inclined as indicated at w6 in such a way as to co-operate with the sliding wedge to draw the shaft w* downwardly against the action of the spring u, as will be obvious from Figs. 3 and 4. The handle W is secured to one arm of a bell crank lever w7 which has pivoted thereto links w8 and w9 connected respectively to the rack w and the sliding wedge wz.

The roller V which, as before stated, serves to guide the forward end of the member f5 may be journaled in a carrier o which is pivoted at 'u' to a bracket o2 suitably secured to the guide rail G. Thus the roller may be swung into and out of operative position, it being held in operative position by some such means as a pin and slot connection, illustrated particularly in Fig. 7. The pin is the front of the machine which is operatively The upper surface preferably provided with a spring v3 con-v tained in a suitable housing and acting upon the forward end of the pin which is enlarged for this purpose.

When the attachment is not in use, the roller o is allowed to drop intojfthe position shown in dotted lines in Fig. 2 and the bracket arm U is swung out to the position indicated in dotted lines in Fig. 1. is desired to use the attachment, the arm F is swung toward the right in Fig. l and the handle W is depressed thus swinging the bracket arm U into position. It will be understood that when the bracket arm U is swung into position, the shaft a4 will be raised enough by the spring u to permit the bracket arm to swing around above the plane of the detent u2, and that the rack and sliding wedge are so related to each other that as soon as the bracket U has been swung into operative position, the wedge will act upon the collar w3 and will depress the shaft a4 thus bringing the bracket arm down so that the detent a2 will engage the recess therein. When the bracket arm has been swung into operative position, the roller V is raised and fastened by means of the pin and slot connection above described in the position indicated in full lines in Figs. 2, 7 and 8. lever F is brought into the position indicated in Fig. l with its end F2 resting upon the roller V, and the screw f 9 is unfastened so as to free the member f5 from the member f6. The device then is in readiness for cutting a straight edge or otherwise operating along a straight line. When it is desired to disconnect the attachment from the elbow lever and to use the machine in the ordinary manner, the lever is brought again into the position shown in Fig. l, the handle W is raised thus swinging back the swiveling bracket U and the roller V is unfastened and swung down into the position shown in dotted lines in Fig. 2.

It will be Aunderstood that various changes may be made in the embodiment of the invention shown and described herein and`that it is not limited therefore to the construction shown nor to the use in connection with which it has been particularly described.
